Heya,

 

Happy mother's day to all, hope you have a wonderful weekend or memory of your loved ones!

 

I was able to get a little sky time this morning, a quick 20ish minute session. Seeing was fairly good this morning with a much smaller temperature delta as my summer weather is rolling in after a weird cold snap in early May here in Florida. AR2822 presented in photosphere and the upper & lower chromosphere at the same image scales.
